PlanckForth - ein minimales Linux-Forth
PlackForth ist ein Linux-Programm als handgeschriebene ELF-Linux-Datei (ELF = Executable and Linking Format - Dateiformat für ausführbare Dateien unter Unix/Linux). D.h PlankForth liegt nicht im Quelltext als Assembler oder Hochsprache vor, sondern wurde vom Autor Koichi Nakamura manuell in einer Hex-Datei geschrieben. Diese Hexdatei ist der "Quellcode" und wird in Binärcode "übersetzt".
Das Ergebnis ist ein minimales Forth mit 37 Forth-"Wörtern" die jeweils aus nur einem Buchstaben (bei Unterscheidung von Gross- und Kleinschreibung) bestehen. Das resultierende Binärprogramm ist genau 1024 Bytes gross, also doppelt so gross wie SectorForth.

Liebe Freunde des gepflegten Alteisens! Kommendes Wochenende ist Vintage Computing Festival Berlin 2020 https://vcfb.de/2020/), und ihr könnt das alle besuchen, ohne auch nur einen einzigen Fuß vor die Tür zu tun. Ich bin dieses Jahr leider nur passiv dabei. Schade finde ich insbesondere, dass dieses Jahr die Fotografiererei auf der Strecke bleiben wird: https://www.flickr.com/search/?user_id=52924836%40N00&text=vcfb&view_all=1 #vintagecomputing #retrocomputing #vcfberlin #vcfb
Forth benchmark competition and Forth "live-coding" tomorrow @ VCFb
Thanks to various expressions of interest & support, I've freshened my old ForthOS. It builds its own GDT/IDT, has a proper RTC handler, and all I/O is interrupt based (previously it was a polled system). On qemu it no longer pegs the host CPU at 100%. It's still free, open source, and so forth. Try the new image disk image (source included):
